S. Jenmani, Hemsl., figured at t. 2649 of this work. Although appa- 
rently identical in their vegetative parts, the two species may be 
readily distinguished by a remarkably interesting difference in the 
form of the inflorescence. 
male spike with two very short lateral branches at the base, which 
bear the female flowers. During the flowering stage of the male these 
and bear fruit. In the fruiting stage the large scar left by the male 
at the point where it articulated is always plainly visible in the sinus 
of the two infructescences. It seems probable then that the females 
become fully developed either at the end of the season and are 
pollinated by flowers from younger inflorescences, or at the begin - 
ning of the next flowering season when fresh male flowers are matured 
on other parts of the plant. 
e growth of the two species under cultivation has been observed 
to be different: the primary branches of S. Jenmani are directed 
upwards and form an acute angle with the stem, whilst those of 
S. cladogyne spread from it almost horizontally —J. Hurcuinson.
